Describe your request

I ran into an issue where I am trying to use a more powerful server to cross-compile SurrealDB to my RaspberryPi 4 - and, as I tried it, this happened:

Therefore, I'd love for cross to better support "libc to libc" compiles.

Describe why this would be a good inclusion for cross

Most devices that I know that run on Alpine are small and embedded devices that couldn't support building a huge project like SurrealDB. So this would help them a lot!
